PHP代码在IDE中显示语法错误

Question

I am using the following function as suggested by a friend here to get the innerHTML. While the function works fine and solves my purpose, it is showing syntax error in my IDE. I am not an expert in coding hence not able to figure out. Requesting help in correcting the code.

My code:

<?php

$body = $doc->getElementsByTagName('body')->item(0);

$content = implode(
    "",
    array_map([$doc, 'saveHTML'], iterator_to_array($body->childNodes))
);

echo $content;

My IDE is showing error on this line array_map([$doc, 'saveHTML'], iterator_to_array($body->childNodes))

UPDATE

I use Adome Dreamweaver CS6 as my code editor.

Answer 1

The Dreamweaver CS6 PHP syntax version is 5.3. All 5.4 and later functions/syntax will not be available to it.

Longer explanation for this specific example, shorthand arrays aren't allowed in your editor. If you want the editor to stop complaining you can swap to array() or upgrade to the CC version.

This code will work fine if your actual server is running 5.4 or later.
